To all whom, it may concern:

Be it known that 1, HUGH CROWE, of the city of Eldon, Miller county, State of Hissouri, have invented certain new and useful Improvements in Apparatus for Moving Steam Shovels, Excavators, or the Like, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My object is to construct an improved apparatus for moving steam-shovels, excavators, and the like; and my invention consists of the combination, with a steam-shovel, excavator,or thelike,mounted on wheels and adapted to run on a railroad, of means of raising the rails from their position behind the machine, means of moving said rails out of line of the wheels, means of drawing said rails forwardly to positions in front of the machine, and means of reversing the apparatus to run backwardly, if desired.

Figure 1 is a View in elevation showing a steam-shovel or excavator in dotted lines on a railroad, showing my improved apparatus applied thereto in full lines. Fig. 2 is a detail view illustrating the boom employed in raising the rails from their position and moving the rails to one side of/the wheels. Fig. 3 is a top plan view of the rear end of the boom shown in Fig. 2. Fig. 4: is a top plan view of the parts shown in Fig. 1. Fig. 5 is a cross-section of the track and showing a pulley and hook employed in raising the rail. Fig. 6 is a perspective view showing a runner mounted under a rail, so that the rail may be easily drawn.

Referring to the drawings in detail, the excavator 7 (shown in dotted lines) may be any form of steam-shovel or excavator. The bar 8 is secured to the rear end of the bed of the machine 7 by bolts inserted through the openings 0, and the ends 10 of said bar are bent downwardly and secured to a similar bar 11, said bar 11 being parallel and a short distance below the bar 8. Arms 12 extend backwardly from the ends of the bars 8 and 11, and the rear ends of said arms are connected by a rod 13. The boom 14: is placed in horizontal position, with its rear ends between the bars 8 and 11, and a grooved wheel 15, connected to the rear end of the boom 14, engages the rod 13, so that the boom may be moved back and chine.

forth crosswise to the rear end of the machine. A stop-bolt 16 is removably inserted through the'b'ars'S and 11 to be engaged by the rear end of the boom 1a to hold said boom at one side or the other of the machine, as desired. Guy-ropes 17 are attached to the rear end of the boom and extend upwardly and forwardly over the posts 18, said posts extending upwardly from the bed of the machine 7, and the forward ends of said ropes 17 are attached to the rigging at the forward end of the ma- A second guy-rope 19 is attached to the rear endof the boom and removably attached to one corner of the rear end of the machine, as shown in Fig. 1, said rope being movable from one corner to the other when the boom is moved from one side to the other. A pulley 20'is attached to or suspended from the rear end of the boom 1d, and the drawrope 21 extends over said pulley and has a hook 22 on its rear end to engage the rail, and said draw-rope 21 extends forwardly over a pulley 23, secured to the dipper or shovel at the extreme forward end of the machine, and then backwardly to the Windlass 24.

When the machine is standing on the rails 25, the hook 22 is placed in engagement with one of the rails 26 and the windlass is operated by the engine to raise said rail 26 upwardly from the track-bed and draw said rail out of line of the wheels of the engine. Then the Windlass is backed to slaeken the rope 21, and the rope is removed from the pulley 20 through the slot 27 and dropped onto the ground. Then the Windlass is again operated to draw the rail 26 to a position in front of the rails 25. Then the rails 26 are adjusted in position in line with the rails 25 and the machine may be run forwardly onto the rails 26. Then the rails 25 may be removed in a similar manner. In this way it is possible for the excavator to travel any desired distance, making its own road-bed and laying its own track by the use of two pairs of rails.

A set of cross-ties 28 may be employed for each pair'ot rails, said cross-ties being connected together by the chains 29, so that the cross ties may be moved and drawn for wardly, one set at a time, in a mannersimilar to the movement of the rails. the rails may be mounted upon runners or stringers 30, as shown inFig. 6, so that the If desired,

' rails will readily slide along the soft roadbed, each runner being rounded, as indicated by 31, said runners being wider than the rails to form a support to keep the rails from sinking into the soft road-bed. The cross-ties 28 may be omitted. The pulley 23, being attached to the dipper 32, may be moved from one side to the other of the machine corresponding to the motion of the pulley 20, attached to one end of the boom 14, or, if desired, the second boom 1% may be employed instead of the dipper The boom 14 is of such a length that when the machine is properly located upon the rails 25 the hook 22 may readily be inserted into an opening in the middle of one of the rails 26, and the pulley is as far in front of the forward truck 33 as the pulley 20 is behind the rear truck 34, so that the machine may be moved forwardly or backwardly, as desired, simply by reversing the operation.

If the road-bed is narrow or unsuitable for hauling the rails outside of the truck, the rails may be moved inwardly and passed forwardly between the wheels of the truck.

Screw-eyes 36 are attached to and extend inwardly from the rails, and rods 35 have their ends bent to hook into the screw-eyes 36, as required, to hold the rails the proper distance apart.

I claim- An apparatus of the class described comprising the combination with a steam-shovel, excavator or the like; of two pairs of rails; bars removably hooking said rails together in pairs, one pair of said rails being adapted to support the machine while the other pair is unhooked and separately removed from one end of the machine to the other; runners mounted under said rails; means of raising said rails and runners from the road-bed out of alinement with the wheels of the machine; and means of drawing said rails and runners from one end of the machine to the other, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

HUGH OROWE.
